The invention relates to the field of detection of batteries of electric automobiles, in particular to a dynamic intelligent detection device and a detection method for a storage battery of an electric automobile. The dynamic intelligent detection device for the storage battery of the electric automobile comprises a voltage sensor, a current sensor, a temperature sensor and a pressure sensor which are in signal transmission with an ARM (Advanced RISC Machines) processor through a data bus CAN (Controller Area Network), wherein the voltage sensor, the current sensor, the temperature sensor and the pressure sensor are all in signal connection with the storage battery, and the ARM processor is respectively in signal connection with an LED display, a buzzer and a storage. The ARM processor is further provided with a plurality of open interfaces. The detection concepts of local concentration, overall distribution, dynamic real-time detection, and intelligent judgment prompt are proposed, that is, all batteries are divided into a plurality of small groups, each small group uses one detection module to carry out dynamic real-time concentrated detection, and the whole system uses a plurality of sensors to acquire data and transmits the data to the ARM processor through the connection of the CAN bus.
